For more information about the ignition system, see subsection 7.7.

The fuel injection system works as follows:

A fuel pump installed in a fuel tank, takes fuel from the fuel tank to the fuel manifold through the filter mounted on the rear wall of the engine compartment.

The pressure in the fuel system is controlled by a pressure regulator, which is mounted on the side of the fuel reservoir.

Pressure regulator rises to an excess of fuel could go back into the fuel tank when the fuel pressure exceeds the optimum.
